bagged top - a method of binding the top line of an upper so that
no stitches can be seen, giving a very soft feel and look.
ball - the swelling at the inner side of the foot where the
big toe joins the head of the first metatarsal bone. The main line of
flexing of the foot, and hence of the shoe occurs across this point,
which is therefore
important in shoe fitting. This part of the foot is sometimes referred
to as the joint.
ballerina - flat heeled (not more than one lift) pump
designed to resemble ballet shoe.
ballet shoe - a very light type of heelless
shoe with upper of satin or other fabric, designed for ballet dancing.
Held on the foot by ribbons, arising from the quarters on each side,

forepart upper is attached to the insole with hot adhesive instead of
tacks.
cemented construction - bonding the sole of the upper by
means of a cement, usually heat and pressure activated. This produces a
shoe which is light, flexible and neat, as well as being cheaper to
produce than more traditional methods. It is much used for light dress
shoes and unit soles. If the bonding is not correctly carried out the
sole will come away from the upper.

Children's Foot Health
Register - in
an effort to improve the foot health of the children of this country,
the Children's Foot Health Register has been compiled, listing retailers
in geographical locations who have undertaken to have shoes in stock in
a choice of four width fittings in full and half sizes, and who have
staff trained to measure the feet and width and fit correctly at the
time of sale. The minimum requirements are that footwear for children is
available in the shop in whole and half sizes from infants size 3
through to girl's and boy's size 5 in four width fittings. In addition
members are expected to carry a minimum stock of sandals at the start of
the summer season in full and half-sizes and four width fittings. The
Children's Foot Health Register is revised annually. Details from the

Htting shoe - shoes made in more than one
width in each size. the width is commonly indicated by a letter or
number. Practice varies in detail but the general scheme of width
markings for women's shoes made in the UK is: narrow-AA, A, B, C:
medium-D, E, broad-F, G, H. Corresponding number marking for the three
groups would be: 1, 2, 3, 4, 5, 6, 7, 8, 9. In men's shoes the UK
classification of fittings is approximately:
narrow-A, B, C; medium-D, E, F; broad-G, H; and corresponding number
groups, 1, 2, 3, 4, 5, 6, 7, 8. UK practice is usually a difference of
5mm in joint girths between consecutive whole sizes up to children's
size 10, and 6.5mm difference between joint girths of sizes above 10.
The classification of width measurements as narrow, medium and broad can
only be an approximation. There may be differences between one
manufacturer's scale of fittings and another's arising, for example,
from fashion changes of forepart shape.
flash - rubber or plastic which, in a moulding
operation, may exude from the mould through minute gaps at the mould
parting lines, or where the feather meets the side moulds in
direct-moulding. It must be trimmed off by hand or machine, which is
difficult to do perfectly.
flat foot, pes planus - clinical features of this
condition are a tilting inwardly of the os calcis and displacement of
the head of the astragulus downwards. The result is an inward tilting of
the heel, observable from the rear when the sufferer is standing.
another feature is abduction of the foot, that is, displacement of the
forefoot outwardly or away from the median line of the body. This is
sometimes called pronation. A result of the changes described is that
the inner border of the foot is lengthened. Arch supports of various
kinds and the shoemaking practice of providing a built-in support by
raising the inner side of the waist of the shoe have probably helped to
prevent cases of weak foot or incipient flat foot from becoming worse.
Chiropodists can offer diagnosis and recommendations for exercises and
re-education of the sufferer's attitude in walking, which is said to be
an important remedial factor. The shoe fitter clearly has a problem in
providing from his stock a shoe with forepart design appropriate to
accommodate even a moderately pronated foot. A wide-fitting nature form
shoe and an arch support may be worthwhile lines of approach.
flesh, flesh side - the inner side of an animal skin
or piece of leather; opposite to the grain, grain side, or outer side.
floppy disc - plastic disc with metallic
coating which can store electronic signals. Used in computers to store

from an original model in cold curing silicone rubber. Reproduction is
achieved by pressing PVC upper material against the mould in a special
press where it is subjected to high-frequency, high-voltage electric
current which momentarily fuses the PVC by molecular excitation. This
process enables complex designs in leather uppers to be copied in PVC
very cheaply.
folding - the most usual word for an upper edge
treatment where a narrow margin of the edge is folded over, skived and
secured by adhesive. A few areas in the UK call this operation beading.
foot beds - an insert which is shaped or moulded to
match the approximate contours of the bottom surface of the foot. Such
insets are widely used in trainers and sports shoes.
Footwear Testing Center - set up as a result of the
footwear code of practice the testing center acts as an arbitrator when
disputes occur over faulty footwear between the customers and the
retailer. Its address is 249, Rockingham Road, Kettering, Northants
(01536 410000). The center is not able to deal with shoes sent in by
private individuals.

attached by cement vertically runlet; the edge of some shoes. When in
crepe sometimes known as a curtain.
french binding - a method of finishing the
topline by binding it with a tape of fabric or plastic material.
Sometimes called galloon binding.

are laid over the vamp and drawn together by a lace. Sometimes called; a
lorne shoe it is the women's equivalent to a men's derby.
gimping - saw-toothed edge to leather resembling
pinking in fabric.
girth - the measurement round the wide part of the
foot, namely the ball or joint. Used in several shoe fitting systems
instead of simply the width. It is superior to the width system because
it is possible for two people with the same foot width to have different
joint girth measurements. The width system takes no account of the 'depth',
that is the thickness of the foot a the forepart. The fitter takes
account of it when he sees the customer's foot and suggests an
appropriate width fitting.
glace kid - upper leather made from chrome(
tanned kidskin, finished with a smooth glossy surface. Also
called glazed kid.
glazed goat - similar to glace kid, but from
adult animal. The grain is coarser, and the leather more inclined to

peculiarities, characteristic of the animal concerned, visible on the
outer surface of a hide or skin after the hair or wool has been removed.
grain layer - the layer of a hide or skin
extending from the surface after removal of the hair or wool and
epidermis down to about the level of the hair or wool roots.

vamp both curving downwards to overlap on both sides near the sole,
leaving a V- shape cut-away appearance at the waist.

stapling wire, etc., used in shoemaking.
H
half d'Orsay - similar to d'Orsay but only
outside of court is cut out.
half-sole - sole covering the tread or forepart of the
foot only. It is much cheaper to replace a worn sole with a half sole
than a long sole.
hallux rigidus - a painful affliction of the big
toe, with restriction of movement, the toe being held in the extended
position, or sometimes slightly dorsiflexed. Very little, if any,
dorsiflexion is possible. In a related condition, hallux flexus, the toe
is rigidly plantar flexed.
hallux valgus - a sideways deviation of the big
toe toward the other toes. It is associated with the development of a
prominence on the inner side of the joint, which then develops a
protective bursa. The bursa may become inflamed, resulting in a bunion.
The first metatarsal head, or joint to which the shoe fitter takes the
heel- to-ball measure, is much more prominent than is normal, and the
forefoot is wider because of the larger than average angle between the
first and second metatarsal shafts. The condition is often found in a
foot with a larger than average angle between the first and second
metatarsal shafts, which is an inherited characteristic. The cause of
hallux valgus is not clear. It may be pointed toe shoes, shoes fitted
too short or too narrow, or a combination of
any of these with a foot structure that has a
predisposition, possibly hereditary, towards the abnormal. Women are
sufferers much more frequently than men, perhaps by as many as ten to
one. Because the foot is extraordinarily insensitive to distorting
pressures of all kinds, even from child-hood, sufferers often do not
seek advice until it is too late for simple remedial measures.
Chiropodists have various means to prevent early cases from becoming
chronic and are also able to give sound advice about the choice of
footwear, as are qualified shoe fitters. It is absolutely essential,
nevertheless, that the condition should be diagnosed early.
heat setting - giving an upper more permanent
shape retention while it is on the last by the application of heat or
steam for a short period instead of a longer period under strain.
heel attachment - by barbed nails, screws or
staples. It is vital that this is correctly done, particularly in the
case of high heels, otherwise the heel may come off.
heel to ball measure - the measured distance of the
ball of the foot from the heel end. A shoe selected to fit the foot
should have a corresponding measure from heel to widest part of the
forepart. The relationship of this measure to the total foot length is
the basis of the Brannock system. See Brannock device.
heel breast - the front surface of a shoe heel.
heel grip - small suede-covered pad which can be stuck
to counter lining of shoe to reduce size at heel and prevent foot
slipping out of shoe.
heel height - the vertical distance from the
center of the top-piece where it contacts the ground to the seat of the
shoe. There is, however, much difference of opinion as to how this
measurement should be taken, because of differences of seat angle with
the horizontal and top-piece location in a fore and aft sense. The above
definition assumes that the center of the top-piece is vertically below
the center of pressure of the weight-bearing protuberance of the lower
surface of the heel bone. In practice the height is most commonly
measured at the back of the heel, vertically upward from ground surface
to seat.
heel pitch - angle between axis and heel and base line.
If heel axis is not vertical damage may result.
hide - the outer covering of a mature or fully-grown animal
of the larger kind, for example cattle, horse, camel, whale. In France
the word is used for adult bovine animals only. In Germany, it also
applies to pigs, reptiles, fishes and birds.
hollow foot - see pes cavus
house shoes - another name for slippers, used
in the language of some countries in Europe where a stouter construction
is
sometimes made. See Albert slipper and Grecian slipper.
Some slippers are made by the moccasin construction.

Infra-red - heat radiation. Radiation in the spectrum of
electromagnetic radiations of wavelengths longer than visible light and
shorter than radio frequencies. Not visible to the naked eye.
injection mouldlng - a method of moulding a sole unit,
for example, using PVC or other thermoplastic material, by melting the
material in the heated barrel of an injection moulding machine and
injecting it under pressure into the mould cavity. This is a cheap
method of mass- producing shoes. The sole is flexible, waterproof
long-wearing, with excellent adhesion, but tends to crack after a while.
Insock - a thin layer of materials put in to the shoe
after manufacture to cover the insole.
insole - light sole conforming to the shape of the
bottom of the last to which the upper and the bottom are attached to
make the shoe. In most constructions, therefore, it forms the foundation
of the shoe. It is made of leather, leatherboard or fibreboard, and
needs to be flexible and able to absorb moisture. In many cases it is
covered by an in sock after making to cover any nails, stitches, etc.
which may protrude.

injection moulding process. Usually produced in complex open designs for
casual and summer use.
Joggers - see trainers.
Jolnt - see ball. An enlarged joint is called a
bunion.
Just In Time (JIT) - a method of organizing the
manufacturing or business processes so that raw materials, components
and sub-assemblies arrive just-in-time at the required point of
manufacture. It is aimed at minimizing stocks before, during and
dramatically speeding up throughout times. Teamwork and modular
manufacturing systems are often employed with this approach.
L
laces - the length of a lace must be appropriate to
the number of eyelets in the shoe for which it is intended. The table
shows the usual classification.
lamlnatlon - joining the faces of sheets of materials
together. This gives greater strength than each material would have on
its own, and simplifies handling. Examples are laminated linings, which
are cut at the same time as the outers, and brittle leathers such as
snakes which are laminated to a backer to prevent splitting in lasting
and wear.
last - a solid form of wood, plastic or metal on which a
shoe is built, and which imparts its shape to the shoe. When the sole
has been attached the last is removed, and the inside dimensions of the
shoe should then conform to those of the last.
lasting tack - small tack used to secure upper
to insole. Also used for temporary attachment of insole to last, in
which case it must be removed before sole attachment. If this is not
done customer dissatisfaction will certainly result.
lasting - the operation of stretching the upper over
the last so that is conforms to the shape of the last, at the same time
attaching it to the insole.
latex - the milky emulsion of rubber particles
exuded from the bark of the rubber tree. It is coagulated to separate
the water, leaving the natural rubber. Used for making natural crepe
rubber and adhesives. When vulcanized it is the rubber widely used for
soling, often in combination with synthetic rubber.
leather - hide or skin which retains its original
fibrous structure but has been treated so that it will not rot even
after absorbing water.
leatherboard - sheet material made by shredding
pieces of scrap leather, suspending it in water together with a small
percentage of rubber or synthetic binding material, depositing it on a
wire mesh or similar support to agglutinate, and then drying. Used for
insoles, etc.
leather, chrome tanned - leather tanned either solely
with chromium salts or with chromium salts together with quite small
amounts of some other tanning agent used merely to assist the chrome
tanning process, and not in sufficient amount to alter the essential
chrome-tanned character of the leather.
leather goods - articles from suitcases and
purses to watchstraps.
leather, vegetable tanned - leather tanned exclusively
with vegetable tanning agents, or with such materials together with
small amounts of other agents used merely to assist the tanning process
or to improve or modify the leather, and not in sufficient amounts to
alter notably the essential vegetable-tanned character of the leather.
lifts - layers of leather or leatherboard composing
the heel of a shoe. the lift in contact with the ground is called the
top- piece and is frequently of rubber or plastic.
linlng - the inner surface of the shoe upper. Linings
may be used in just the back of the shoe or as full linings covering the
whole of the shoe interior.
loafers - a light-weight casual for men, without
fastening. Usually with a small tongue and saddle trim.
lorne shoe - see gibson.
louis heel - a shaped heel, usually curved in at the back
and sides, with a breasted forepart.
M
made-to-measure - nominally the same as bespoke,
but is in common use to denote shoes made an a stock last which
approximately corresponds to the measurements of the customer's foot.
magnetorestriction - a change in the dimensions of
ferromagnetic substances (for example iron, nickel and cobalt), when
they are magnetized. (See ultrasonics.)
magnetron, cavity magnetron - a thermionic valve for
producing high power microwave oscillations. Used in large conveyorised
machines for drying leather.
mallet toe - see hammer toe.
management information systems (MIS) - computer system for linking all
departments for more efficient company management.

other uses, wiping the surface of PVC mouldings to remove plasticiser.
As with all solvents ventilation of the working area is important.
metalllsed leather - leather given a lustre finish by
the application of metallic powders or foils.
metamerism - a peculiarity of colours whereby two
materials judged to be an identical colour match by one light appear
markedly different by another light.
metatarsal bones - the five longest bones in the
foot, extending from the toes to the cuboid and cuneiform bones of the
instep.
metatarsalgla - an extremely painful condition
of the forefoot, starting with a burning sensation in the fourth
metatarsal head region. This develops suddenly into a severe piercing
pain extending to the tips of the fourth and fifth toes. This true
metatarsalgia was first described in 1876 by a Dr Morton of Philadelphia
and has sometimes been referred to as Morton's neuralgia or Morton's toe.
The cause is pressure on the nerves near the metatarsal heads when
walking, arising from some degree of displacement of the metatarsal
heads. Treatment by chiropody includes the fitting of a suitably skived
felt pad behind the heads of the metatarsals affected, or the fitting of
a metatarsal bar to the insole or outsole. Cases of Morton's
metatarsalgia are rare. Women are affected more than men. Not all
painful forefoot conditions are attributable to it.
MICAM - Modacalzatura, Bologna and Milan, Italy.
microcellular - a characteristic of elastomeric
soling materials which have innumerable tiny cefls
of gas through-out the structure, promoting lightness and a cushioned
feeling underfoot. The cells are often too small to be discerned by the
eye.
mlcron - micrometer. On millionth of a metre, or one
thousandth of a millionstre.
Symbol is a Greek small mu (u).
microprocessor - a microelectronic device with a
memory that can be set to programme a series of, for example, mechanical
movements of an arm with a grasping device to move shoe component from
one machine to another. It is much simpler than a computer, differing
from it in not having a central processor unit, or print-out or other
peripherals.
midsoles - a half sole placed in the forepart of the
shoe.
mineral tannage - tanning with salts of metals,
for example chromium, aluminum, zirconium.
MIPEL - bag and leathergoods show, Milan, Italy.
MOCAP - Portuguese shoe show in Oporto.
moccasln - a shoe construction in which the upper and
sole are in one piece, and the shoe is closed by stitching in the vamp,
not at the back as is usual. The original Red Indian moccasin was made
from heavy hide and has no outsole. These are now generally used for
indoor use. For outdoor and dress wear light leathers, such as glace kid,
are used and an outsole and heel are attached to the bottom. In his case
the adhesion at the feather edge can be a problem. Moccasins are
flexible and comfortable, but are not recommended for heavy wear. As a
general rule they can be identified by the absence of an insole, which
gives the shoe its flexibility, but some makers insert an insole to try
to give greater strength, in which case the resulting product cannot
truly be described as a moccasin.
moccasln front - vamp having an apron front which
appears to have been made by the moccasin method, but is only an
imitation.
MODATECC - International Fair of Technology and
Footwear Fashion. Elda, Spain.
Morton's neuralgla - see metatarsalgia.
monomer - a material consisting of single molecules of
a chemical compound. (See polymer).
MSRA - Multiple Shoe Retailers' Association.
Mondopoint - an intended international method of
designating shoe sizes. It provides that the marking should consist of
two numbers: (1) a number corresponding to the length in millimetres (measured
weight-on and wearing hose) of the average foot fitted; and (2) a number
corresponding to the joint width in millimetres (measured weight-on and
wearing hose) of the average foot fitted. Mondopoint has been adopted by
the Sritish Standards Institution and the International Standards
Organisation, which have specified that the size interval should be 5 mm
or 7 mm, depending on the type of footwear. For example, 5 mm would be
appropriate for women's court shoes and 7mm for footwear for which
fitting tolerance is not so critical, such as moulded footwear. When a
range is graded by the 7mm scale it is proposed to mark increases in
size by alternate increments of 7 mm and 8 mm, for example, 240, 247,
255, 262, 270.
monk shoe - a shoe fastened at the instep by a broad
strap with buckle towards the outer side.
mule - a slipper or shoe without quarters, held on the foot
by the forepart only.
mulllng - part of the making process. Uppers are
warmed and damped by steam to make them more pliable and easier to last.
N
NAMSR - National Association of Multiple Shoe
Repairers.
nature-form shoe - a shoe with straight inside
edge, low heel and adequate width for joint and toes, designed to be as
close as possible in shape to the natural foot.
Neoprene - trade name used by Du Pont for the synthetic
rubber, polychloroprene, developed in their laboratories in 1931. Widely
used as an adhesive in shoemaking and in soling compositions.
non-woven material/non-woven fabric - sheet material comprising fibres
felted or bonded together, or interwoven by the needle-loom'process.
Widely used as a substrate for coated materials and in poromerics, and
as a reinforcement for shoe uppers.
non-woven Insole material - made from random laid
synthetic fibres and bonded with a small proportion of synthetic rubber
or other polymeric materials.
nubuck - stout hide leather, buffed on the grain side
to give a velvety surface.
nylon tape - used for reinforcing lines and points of
weaknesses, particularly straps and top-lines.
O
onychogryphosis - gross over development of the
nail, usually of the big toe, caused by trauma or infection. Growth of
the nail from the proximal aspect of the nail bed is accelerated in this
condition, causing the nail to grow upwards and forward, producing the
characteristic ram's horn appearance. It is common in elderly and
bedridden patients. The chiropodist has equipment for reducing the nail
overgrowth.
oxford shoe - a man's style with closed front,
that is with the quarters stitched under the vamp. (Compare derby.) The
style above is an oxford full brogue.
P
parchment - translucent or opaque dry untanned skin or
hide with an even surface intended, for example, for writing of
bookbinding.
paris points - the system of shoe size
measurement common over most of the continent of europe. There are three
paris points of two centimetres, so that one is equal to two-thirds of a
centimetre. The size scale starts at zero.
patent leather - leather which has been given a
shiny finish. Originally this was applied by a linseed oil based
dressing, but it is now usually plastic. Note that a patent finish can
be applied to leathers of widely differing qualities, so that it can
vary from light and supple to heavy and rigid.
pearllsed - leather finish giving a lustrous appearance,
similar to the appearance of a pearl.
permeabillty - the ability of a material to
transmit water or water vapour through its thickness. The comfort of a
leather shoe is due in part to this property of leather.
Personal Protective Equipment (PPE)
- any product designed to be worn or held to provide protection,
pes arcuatus - see pes cavus.
pes cavus - a foot deformity characterised by a greater
than normal degree of arching of the foot. Various degrees of the
condition may be known as claw foot, hollow foot, pes arcuatus) and
talipes plantaris. In the normal foot the degree of arching varies
greatly. In minor cases of pes cavus chiropodists fit metatarsal pads to
raise the anterior metatarsal region. More severe conditions may need
surgery.
pes planus - see flat foot.
petrol patent - a black patent leather which is
finished to give a subtle multi- coloured, prismatic effect resembling
petrol split onto a wet surface.
pH - a measure of the acidity or alkalinity of an aqueous
medium, based on the hydrogen ion concentration. Pure water is 7. A pH
below 7 indicates acidity. A pH above 7 indicates alkalinity.
phalanges - the toe bones, two in the big toe and three
in each of the others.
pigment finish - a leather finish containing fine
particles of pigment. In some cases this amounts to painting the leather,
as opposed to dying it.
piping (of uppers) - upper decoration formed by
placing string under material, and stitching along it, giving a raised
strip.
piping (of leathers) - tendency for surface to crease
when flexed.
pitch - the angle at the joint between the sole. and
the ground. It should be greater on -high heeled shoes than low.
Incorrect pitch is often a sign that a heel which is the wrong height
for the last has been used.
plantar - the lower surface of the foot. Sometimes
used to describe the insole.
plantar flex - a foot movement. To flex the
foot downward so that the forefoot moves further away from the leg.
plastic upper materials - in ever-increasing use,
and have undergone considerable advances in recent years. The two main
Materials used are PVC and PU, both laminated to a textile backer. The
best PUs have the feel of leather and their surfaces are finished to
give the look of fine leathers. While not necessarily cheaper than
leather, they save labour in the factory and are more adaptable to mass
production methods due to their homogeneity. In some cases they are hard
to distinguish visually from leather, clues being a tendency for the
stitches to sink into the material, and a reluctance on the part of
designers to leave edges raw. They hold their colour better than leather.
Disadvantages are their non- permeability, which can cause hot and
odourous feet, and a tendency to crack after extensive wear. They also
do not keep their shape as well as leather.
plasticiser - a chemical component included in
polyvinyl chloride (PVC) to make it flexible for use in soling, for
example. The lower cost platicisers have an oily character. They tend to
migrate, which causes adhesion problems and changes in the character of
the soling. Non-oily plasticisers, fully compatible with PVC, have been
introduced to improve quality.
platform - an extra component inserted between the
insole and the outsole to add height to the wearer, or to give a chunky
look to shoe design. The heel height has to be increased to accommodate
the extra height. Platforms are made of various plastics, cork grain or
even wood. In some cases they are moulded in one piece with outsole and
heel.
pleating - folding of upper leather to give a gathered
effect. It is regular, as opposed to ruching, which is random.
polyamide - a class of plastic materials of which nylon
is the representative example. Used for woven materials and hot melt
adhesives.
polyester - a plastic material much used of thread,
alone or blended with cotton for fabrics, and for hot melt adhesives.
polymer - a chain or other co-ordination of single
molecules of a chemical compound.
monomer polystyrene - a polymer of the monomer styrene.
A rigid plastic much used for plastic heels.
polyurethane (PU) - synthetic soling material.
Expanded PU is produced by mixing two chemicals which combine inside the
mould to produce polyurethane foam. As little heat or pressure is
involved the moulds are relatively cheap and easy to produce, allowing
relatively short runs. It is flexible for use in bottom units which are
soft and light, wear well and resist slip. There is a rigid version
which is used for platforms.
Polyurethane (PU) upper material
- thin sheet of expanded PU with a fabric backer. Usually used in its
lighter weights for women's dress shoes as it has the appearance and
even the feel of a good leather at a lower price.
polyvinyl chloride (PVC) - a synthetic plastic widely
used for soling and coated upper materials, either dense or
microcellular.
poromeric - a word coined by Du Pont and offered as a
generic term.
Porvair - a synthetic upper material made of
microcellular polyurethane with no fibrous base layer. It has a finish
cost simulating the grain of leather. This unique poromeric was invented
and developed in the UK and is still being used in the UK and overseas.
A thin layer of Porvair is used by tanners to combine with leather
splits to make a tough breathable upper material.
POS - Point of Sale pre-finishing. Most soles today are
finished before attaching to the shoe, but some are only finished after
attachment. Welted soles, for instance, cannot be pre-finished.
pre-selection - a designers' exhibition held
before the commencement of the buying season, when buyers and
manufacturers can meet designers and consider and exchange new ideas.
pret-a-porter - ready to wear.
Process Control - a means of ensuring that the
finished product complies with a required standard.
puff - see toepuff.
product liability - the area of the law that deals
with product safety and the legal liability resulting from the supply of
unsafe goods.
pump - light low-heel court shoe.
PVC-coated fabric - used to denote an upper material
made of PVC with a fabric backer. Generally heavier than PU and
therefore used for heavier shoes. It is popular for flow-moulded uppers.
pyroxylin cement - cellulose cement. Solubilised
cellulose held in suspension in a solvent, used as a sole cement.
python - large snake whose leather bears a distinctive
and attractive marking which shows through after drying. It is used for
making shoes, or more commonly on account of its high cost, for insets
and trims. As the size of the scales and the markings vary across the
skin, care must be taken in clicking to match the pieces used. Python,
in common with most other reptiles, tears easily, and it should
therefore be backed. It is not unknown for shoes sold as Python to be
actually made from watersnakes.
Q
Quality Assurance - an effective quality assurance
system is intended top ensure that the goods produced are of saleable
quality, are fit for their intended purpose and offer value for money.
quarters - the two portions of the shoe which cover the
back of the foot. Usually they are joined at the back seam, and are
reinforced by the stiffener.
quartertlp - a segment of a rubber or malleable iron
built into a leather heel top- piece at the back, off center towards the
outer edge where greatest wear occurs.
Quick Response (QR) - an approach to manufacturing
which is aimed at shortening the pipeline from the initial product
design concepts and receipt of orders right through to delivery to the
customer. Emphasis is given to stream-lining all activities, minimizing
work-in-progress and reducing throughout times. It is similar to JIT
manufacturing and often employs modular manufacturing systems too.
R
ram's horn nail - see onychogryphosis.
rand - a strip of leather, or sometimes rubber composition,
cemented to the margin of the sole projecting beyond the feather line,
with decorative notching or bold stitching to simulate a welted
construction.
reactlon moulding - a method of moulding sole units,
direct-moulded sole or other articles in which the moulding pressure is
developed by the chemical reaction of the components which combine in
the mould to form the moulding material. Microcellular polyurethane is
moulded in this way.
resin - an indefinite term broadly used to include
synthetic plastic materials produced by polymerisation. Naturally
occurring polymers such as shellac and rosin, and chemically modified
polymers such as those derived from cellulose are not classed as resins.
The term is in common use to denote resin rubber soling material.
resln-mlx - the mixture of polyester or polyether
chemicals, blowing agent, catalyst system and other ancillary compounds
forming one of the two streams which come together in a moulding machine
to produce polyurethane (PU). The other stream is the di-isocyanate.
resin-rubber - a synthetic rubber soling
material with some superficial resemblance to leather in appearance,
finish and feel underfoot. It is a copolymer of styrene and butadiene,
designated in brief, SBR.
ridlng boot - pull-on knee-high close-leg boot
used for riding. Heel is low, Quality varies from bespoke leather to
plastic moulded. Term also used to denote fashion boot made to resemble
it.
rink systems - a name often used in the shoe
industry to describe modular manufacturing systems, particularly when
applied to lasting and bottom activities.
rub-off finish - a secondary layer of finishing
material applied to upper leather designed to be selectively rubbed off
during shoe finishing to reveal the tighter primary finish, giving the
shoe a hand- made individual look.
ruchlng - random pleating of upper material.
S
safety boots and shoes - footwear with a built-in steel
toe cap designed to prevent crushing damage to the toes. Safety boots
may have, in addition, a non-corrodible steel mid-sole to prevent
penetration by nails, for example, when the wearer is working on
building sites. A recent development has been shoes with an internal
steel cap, qualifying as safety shoes but of fine leathers such as suede
giving them the appearance of good grade walking or town shoes.
Safety toe-caps - a protective toe cap fitted to
safety footwear.
sandal - a simple type of shoe construction in which
the sole is held on the foot by an open-work upper of strips of
material.
SBR - see styrene-butadiene rubber.

now known as the Satra Technology Center. It is an international center
of shoe research, with headquarters and laboratories at Kettering.
SATRASUMM - industry standard system for measuring shoe
patterns and upper materials to produce cutting allowances.
scanning electron microscope
- a microscope which sues a beam of electrons instead of light to
transmit the image. The beam, focused by scanning coils, passes
progressively over the sample in a pattern of closely spaced lines
rather like the raster system of a television tube. The output is fed to
scanning coils of a cathode ray tube, producing the visual image.
seat - the part of the shoe immediately below the heel of
the foot.
seat wheeling - a decorative row of closely
spaced indentations round the top of the heel just below the feather
line.

semi-brogue - brogue decorated only on toecap
and facings for city wear.
semi-chrome leather - leather which has been tanned
with vegetable tannin and then re-tanned with chromium salts.
setting - a process of moistening and then drying by
heat by which the lasted upper is fixed to the shape of the last in a
few minutes so that the last can be released for further use immediately
the sole is put on. Synthetic uppers are heat-set without a previous
moistening or mulling stage as it is called.
sewn-In sock - see slip lasted.
sewn seat - in a welted shoe, one in which the
welt is continued round the heel.
SHALTA - Skin, Hide and Leather Traders Association.
shank - a strip of steel, fibre, wood or leather,
inserted between the outsole and the insole at the waist to maintain the
curvature of the sole and keep the heel from going under. If it is badly
inserted it will click.
shearllng - sheepskin with the wool on, used for slipper
and sometimes boot linings. There are simulated synthetic materials of
this kind for low cost foot-wear. These must not be described as
shearling.
shoe care - covers everything for the care of footwear
from polishes, shoe trees and insocks.
shoe tree - wooden or plastic device inserted in shoes
when not being worn to help them keep their shape. The shoe equivalent
of a cost hanger.
shover - removable piece of leather or other material
attached to a last to add girth at that point only.
side leather - leather made from half of a hide
obtained by dividing the hide along the line of the backbone. As side
leather is usually obtained from larger and older animals, it tends to
be heavy.
SIG - Winter Sports Exhibition. Grenoble, France.
silicon - non-metallic element known in two allotropic
forms. A very pure grown crystalline form is cut into very thin slices
for the manufacture of silicon chips. Electrically it is a
semi-conductor. Distinguished from silicone.
silicone - a chemical compound, analogous to a
hydrocarbon, having a central chain of atoms of silicon, instead of
carbon, in the molecule. Rubbers, oils and greases are possible types of
silicones, each having special properties of great value in industry.
Silicone rubber, when used in certain shoemaking processes, retains its
properties when subjected, in its application in a machine, to
temperatures up to 300"C. It is stable over a very wide temperature
range, down to -90'C. Not to be confused with silicon.
SIMAC - Shoemaking and Tanning Machinery Fair,
Milan, Italy.
sizes - it should be remembered that there are two
different size measurements. (1) foot length and (2) last or internal
shoe length. The differences between lasts are quite large and it is
best to rely on the skill of a qualified shoe fitter rather than to rely
totally on the information from a size-stick or measuring device. These
should be considered as a useful first indication. See also paris points
and mondopoint. Further complication arises when shoes made on European
lasts are imported into the UK. English sizes stamped on the shoes can
never be accurate because English size interval of one third of an inch
is different from the Paris Point increment of 0.66 cm; thus sizes get
out of step.
skl boot - boot designed to be attached to ski. Modern
ones are moulded in PVC.
skl front - tie shoe with apron front which is continued
to form a bellow tongue. The sides of the vamp are usually cut in one
piece with the quarters.
sklve - operation in manufacture where edges of
leather are trimmed down so that the edge is thinner than the body of
the leather, thus reducing the thickness of seams.
sklver - split leather used for linings and socks.
sllng back - shoe with strap passing from forepart round
the hollow of the ankle, usually secured by a buckle.
slip lasted (sometimes called force lasted or tag lasted)
- a simple method of making light casuals or slippers. The upper is
stitched to a sock, which serves as an insole. The last is then forced
in so that an outsole can be attached. A variant is the Californian
which has a platform cover and platform.
SLTC - Society of Leather Technologists and Chemists.
slush moulded - a method of moulding boots from
PVC which reproduces exactly the appearance of the original leather boot
from which the mould is made. As there are no seams the boot is
waterproof. It is usually warm-lined, and is popular for winter wear. It
tends to be rather heavy compared to its leather equivalent.
sock or Insock - a cover of leather or synthetic
material cemented to the insole after the shoe is made to hide tacks or
stitches and present a clean, even appearance. As it is highly visible
it is usually adorned with a brand name and other marketing information.
softee leather - a general term for very soft and
flexible upper leather.
sole attaching - attaching sole to upper of shoe.
solvent - a substance, usually liquid, which can
dissolve other substances. Water is an important solvent but the term is
most generally applied to chemical compounds, such as acetone, white
spirit, MEK, indus- trial methylated spirit, and many others.
spanish heel - a high, narrow, tapered heel
with moderately small toppiece, rather similar to cuban heel but more
incurved.
split - if a hide or skin skiver is split over its
whole area into two or more layers, each is called a split. The grain
split and the flesh split are the most common but in heavy hides there
may also be a middle split.
SPOGA - Sports Goods Exhibition, Cologne, West
Germany.
sponge rubber - see microcellular rubber.
sprue - occurs in moulded or volcanised footwear.
Excess rubber or plastic standing proud where mould is joined. Has to be
trimmed off.
stlffener - a shaped and moulded component, usually of
fibreboard, leatherboard or impregnated fabric, placed between the
lining and upper material at the back of the shoe to improve shape
retention of the quarters.
stiletto heel - a fashion heel having a top-
piece 1cm or less across. It is unsafe to wear and fragile in wear, but
enhances the allure of the wearer, which is the reason for its
popularity. It is important to be sure the heel is strongly attached,
and that the top-piece is properly secured. The thinnest heels should
have a metal reinforcement running from the top-piece to at least half
the height of the heel.
stltching machine, automatic
- the machines are loaded with work by the operator who then starts the
machine-cycle. The cycle is completed automatically - the operator has
no control over the path and a limited control over the speed of
stitching.
straights - shoes designed without distinction of right
and left so that each can be used on either foot.
stretcher - device for stretching uppers after
manufacture. Used for small local adjustments to help fit.
string lasting - a very old process for making
light shoes which has been revived in recent years for conventional
walking and casual shoes. It features a heavy gauge drawstring sewn
round the margin of the flat upper. The upper and an insole are placed
over the last, which is mounted on a jack post, and the operator hauls
the upper closely to the last by pulling on the ends of the drawstring.
The process is additionally interesting for today's conditions because
the last used can be the moulding last of an injection moulding machine,
allowing the sole to be moulded-on without transferring the work to
another operator.
string lasting - type of lasting carried out by
means of two strings attached to the inside lower edge of the upper by a
zig zag seam one for the forepart and one of the backpart and enabling
the upper to be gathered and fastened over the insole.
styrene - a liquid hydrocarbon compound, transformed
to a rigid solid thermoplastic of identical chemical composition by
polymerization. See polymer.
styrene-butadiene rubber (SBR)
- a synthetic rubber introduced into the UK about 1950 by the Goodyear
Tyre and Rubber Co. under the trade name Neolite. It was sold in sheet
form and die cut to sole shapes for adhesive attachment. Its special
properties were that it had tlexibility and adequate wear resistance in
thin substances, and felt and behaved underfoot much like leather, not
like rubber. It is now so widely known and used that soling of this kind
is called simply, resin-rubber.
suede - leather finished with a nap surface by
carefully controlled abrasion. There are many synthetic materials
simulating suede. These must never be described as suede.
suedette, suedene - two generic terms for imitation
suede.
T
tab - any small piece of leather or other material
protruding from the vamp. Can before ornamentation, or to bear a brand
name or eyelet, or to help pull the shoe on.
talipes plantaris - see pes cavus.
thermoplastic - a plastic material which can be
repeatedly softened and remoulded by heat, while retaining the moulded
form in ambient temperatures. See thermosetting plastics.
thermoplastlc rubber - a synthetic rubber related to
resin-rubber but which can be fused by heat and therefore processed into
soles by injection moulding. See resin-rubber.
thermosetting plastics - plastics which retain
permanently their heat-moulded form and are not softened by re-heating.
See thermoplastic.
tle shoe - general name for any shoe held onto the foot
by lacing.
toe post - strip of leather on a sandal separating the
first and second toes, holding sandal on foot either by means of a loop
round the big toe or by straps to the waist. Design originated in India.
toe puff - material inserted between outer and lining
at toe to help it keep its shape. On light fashion shoes plastic is
ironed onto the outer, but in heavier shoes a fibre puff is inserted.
toe spring - the upward curvature or angle of the sole
forepart, relative to ground level, when the shoe is on a level surface.
It is related to the designed stiffness of the sole and the height of
the heel. The more rigid the sole, the greater the toe spring that has
to be provided. Toe spring enables the wearer to proceed by a forward
rolling action at the joint. Without it the foot would be heavily
stressed in an unavailing attempt to bend the sole, leading to tendon
strain and deformation of the long arch.
tongue - an extension of the vamp over the instep,
below the eyelet facings. It covers what would otherwise be a gap
between the facings and protects the instep from lines of pressure from
the laces. A bellows tongue is one cut about double the width of an
ordinary tongue, the sides being folded over the center area and
stitched to the tabs. This make. the tab opening waterproof. Boots so
made are used for fishing and other sports where water is a hazard.
top line - the edge of the upper round the<
throat of the shoe or boot. Usually finished by binding or other
means.
top line reinforcement - in court shoes the top line is subject to
considerable strain, and it should be reinforced by a nylon tape under
the binding to prevent splitting and bursting.
top-line tapes - tapes used for reinforcing
top-line of the shoe.
top-plece or top lift - the layer of leather of a heel
which touches the ground. On leather built heels this needs to be of
best bend leather, but more commonly synthetic materials are used, as
this part of the shoe is subject to the maximum wear. On stiletto heels
moulded nylon is commonly used, an it is important that the top-piece is
very securely attached to the body of the heel.
Total Quality Management (TQM)
- a management philosophy that is aimed at maximum effectiveness and
efficiency within an organisation by putting in place processes and
systems to ensure that every aspect of its activity is aligned to
satisfy customer needs and ensure that every aspect of its activity is
aligned to satisfy customer needs and all other objectives without waste
of effort and using, the full potential of every person in the
organisation. It recognises that customer satisfaction, health, safety,
environmental considerations and business objectives arc mutually
dependent. Central to the philosophy is the concept of striving for
continuous improvement and focusing on fault prevention rather than
detection.
touch and close fasteners - fasteners that cling
together on contact, often suing hook and loop tapes, and are relatively
easily separated.
training courses - retail staff training Diploma
Courses are staged by The Leather Institute. Details from: The Training
Officer, British Leather Confederation, Leather Trade House, King Park
Road, Moulton Park Northampton NN3 1JD (0604 494131).
trainlng shoe or trainer - shoe designed originally
for sports training but both the shoe and the term have come into
general use. Usually has a fabric upper with a leather trim in a lace up
style. Sole is generally either moulded PVC or cemented EVA. It is
common for the manufacturers' brand name or emblem to be prominent in
the design, and this is a major selling point
trichlorethylene - an excellent solvent for grease,
wax and rubber, sometimes used for cleaning shoe uppers in the factory.
It i. highly toxic but non-flammable. Ventilation in the working area is
vitally important.
turnshoe - a shoe made inside-out. The reversed upper
is sewn to the reversed sole and the whole is then turned inside out and
re-lasted. It has been mostly replaced by the cemented method but is
still used for slippers and babies' shoes.
U
UITIC - the Union International des Technicians de
Industrie de la Chaussure, The International Union of Shoe Industry
Technicians. 20 national footwear manufacturers' associations are
members. Conferences are held every two years.
ultrasonics - the study and application of
pressure waves which are of the same nature as sound waves but are
inaudible because they are above the audible limit of about 20,000
vibrations per minute. Electronic technology has made possible the
generation of high power vibrations at these high frequencies which can
be used for welding plastic items together without heat. Note that these
vibrations can only be transmitted through matter of some kind, such as
metal or other solid. See magnetostriction, ultrasonic heel attaching.
ultrasonlc heel attaching - a method of attaching
plastic heels developed by BUSM Co. It uses a strip steel staple shaped
to bridge the shank, having four pointed legs. The staple is placed in a
horn which is vibrated at ultrasonic frequency, causing the staple legs
to char through the seat fibre board and fuse into the heel in less than
a second, locking the shank, insole and heel firmly together.
underfoot comfort - the sue of pressure mapping
technology for studying footwear characteristics which can influence how
comfortable a shoe feels to the wearer.
United Kingdom Accreditation Service (UKAS)
- Official Body responsible for providing independent accreditation of
certification bodies.
UNIDO - United National Industrial Development
Organisation.
unit sole or unit bottom - sole or bottom unit moulded form plastics
material, so that the entire bottom can be attached to shoe in one
operation. As units often incorporate fake welts, rands, foxing, etc.
the unit has to be designed to conform to the last. Some units are
moulded to include leather soles.
upper - portion of shoe which covers the upper
surface of the foot. It can be made of a variety of materials, commonly,
leather, plastics or fabric.
upper leather - light supple leather which can
be lasted over an upper. This usually comes form younger animals, like
calf or kid, or is the result of splitting the hide of an older beast.
Upper leather can be made from the skin of almost any animal,
including reptiles and birds. Cows, goats and sheep are the commonest
sources. The sue of the hides of certain wild animals, such as seals
elephants, rhinos is now severely restricted or banned altogether to
conserve the species. There are severe penalties for illegal dealing in
such hides.
USDAW - Union of Shop, Distributive and Allied
Workers.
V
vamp - the part of the upper between the toe cap and the
quarters, including the toe in the case of capless styles.
vegetable tannage - tanning with vegetable tannins.
The other main group of tanning agents are mineral salts.
velcro - fastening system in which a strip of
material composed of very small plastic hoods engages with an open weave
or looped material. As it is infinitely variable, it is used for
securing bars. It can also be used for attaching trims. This enables
alternative trims to be used on one shoe.
veldtschoen - construction in which the lasted
upper is turned outwards under the welt, this forming a very durable and
waterproof bond.
veldt - similar construction, but with no welt. Less
durable but flexible and comfortable. Commonly used for chukka boots.
verruca, verruca pedis - the plantar wart. This fairly
common affliction on the sole of the foot has some affinity to the
ordinary cutaneous wart except that it has a thick conified outer layer
and most of it is pushed into the dermis by the pressure to which it is
exposed. It is contagious and can be transmitted by walking on the floor
without foot covering or a swimming bath, for example, or a school
dormitory, or by wearing the shoes or socks of someone who is a sufferer.
Chiropodists use a number of curing methods including treatment with
glacial acetic acid, monochlor- or trichlor-acetic acid. One of the
latest treatments is by charring by a laser. The patient can resume
walking almost immediately after treatment. Vascula corns, occurring
most frequently in those with moist skin, have sometimes been described
as verrucae in the stage of involution.
vinyl - commonly used synonym for PVC. More
accurately, the vinyls are a class of chemical compounds of which PVC is
the representative one used in footwear.
virtual reality - advanced computer based 3-D
graphics system with which the user can interact.
vulcanized construction - construction in which
rubber pellets are heated in a mould to form the bottom or a string
lasted shoe. This construction is cheap and produces a flexible
comfortable product, but it can only be used on rough materials like
suede or fabric. It is not suitable for smooth leathers.
vulcanlzed rubber - raw rubber treated by milling
with a sulphur and heat to allow for moulding and to increase durability
and inhibit deterioration.
W
washable leather - leather that can be washed under
normal washing conditions and which has colour fastness, flexibility and
dimensional stability to an acceptable standard under these conditions.
water resistant leather - leather resistant to the
penetration of water, usually chrome tanned or combination tanned,
originally heavily greased but nowadays other water repelling agents may
be used.
wear returns - product returned to the supplier as a result
of its performance in wear being unsatisfactory.
wedge heel - a heel extended under the waist to the
forepart, giving a flat surface in contact with the ground through-out.
Often combined with a platform. See scooped wedge.
welted footwear - a traditional method of producing
footwear. The sole is stitched to a welt, a strip of leather running
around the feather of the shoe, which is also stitched to the upper. One
of the more complex constructions which is now only used for high
quality footwear.
wellington - a calf length boot, of rubber or plastic, for protective war
in conditions of snow, heavy rain, etc. A shorter version, extending a
few inches above the ankle, is called a half-Wellington. The original
wellington boot was worn by the Duke of the same name and was made of
leather.
welt - strip of leather sewn onto insole to which insole is
sewn. Shoes made by the welted construction can be easily resoled by
removing the sole and restitching a fresh one as long as the welt lasts.
A welt should not be confused with a rand, which looks the same but is
merely decorative or a middle sole which has the same appearance but is
not so flexible.
whale oil - the use of whale oil in shoe manufacture is
now banned. It used to be used to make leather more supple.
whole cut shoe - a shoe with the upper cut in one
piece, closed by seaming at the back of the quarters.
width fittings - there are various systems for
defining width. The most commonly used in this country go from AAA to
EEE, very narrow to very broad, with B being the average in women's
shoes, A to G in children's' and D to G (E being average) in men's.
Sometimes numbers 5 to 8 are used form men's. The retailer would be ill
advised to rely on this nomenclature, as it appears to differ from
factory to factory, to the point where some factories refuse to use it
for fear of confusing their customers.
